I experimented with n=6, 7. The idea is simple: by several manipulations with the rope and the first U one can separate the chain into two consecutive chains on the rope consisting one with (n-2) U details and another one with 2 U . Then apply the algorithm for “2-U” and separate the two U from the rope. In this way you obtain a shorter chain and repeat the recursion in the same way. I learned that Mr Strijbos ask puzzlers not to disclose publicly the solutions of his puzzles, so I think this partial disclosure does not destroy your pleasure to find by yourself the recursive procedure. I wonder if he expected that his puzzle can be generalized for arbitrary “n”. Kevin, you can take two additional U from the other puzzle with the ring. Pleasant puzzling, Dimiter.<br /><br /><br />Dimiter Vakarelovhttp://vakarelovpuzzles.blogspot.com/noreply@blogger.comtag:blogger.com,1999:blog-3341941751324943000.post-31306116640799041222014-06-16T09:41:37.573+01:002014-06-16T09:41:37.573+01:00Wow!

I would be interested to hear your exposition on puzzles of level n!<br />The morphology of 2-U is different to 4-U and hence I thought they could not be generalised. But I think you could make a 4-U puzzle with many more Us and have a general solution.

Thanks...Hi Kevin, 4-U is indeed a wonderful puzzle. Thanks for publishing it. I copied it for me and started playing with it. First I learned the version of 2-U (version with only two U details) : easy! Then 3-U, not so easy, but the method was a little update of that of 2-U. The case of 4-U, however, was difficult and I was not able to use my knowledge for 3-U. Finally I found a solution, but this was not an update of the solution of 3-U. I wander if there is a recursive algorithm for “n-U” (n=2,3,4, 5…). I hope there is. What do you think?

Now I can do it blindfolded. I've got the remainder of J. C. Constantin's wire and rope puzzles on order from W. Strijbos. I hope the 4-You is included in that shipment.<br /><br />Cheers,<br />Peter / pcad<br />Peternoreply@blogger.com
